P1441 Dodge EVAP System Flow During Non-Purge Condition
Description: The P1441 code indicates that there is an incorrect flow detected in the evaporative emission (EVAP) system during a non-purge condition.
Common Diagnostic Steps:
- Check for any other stored trouble codes and address those first, as they may be related to or causing the P1441 code.
- Inspect the EVAP purge valve for proper operation. Ensure it is not stuck open or malfunctioning.
- Examine all EVAP hoses and lines for cracks, leaks, or disconnections that could cause improper flow.
- Test the fuel tank pressure sensor to ensure it is functioning correctly and providing accurate readings.
- Verify that the gas cap is properly sealed and functioning as intended. Replace if necessary.
- Perform a smoke test on the EVAP system to identify any leaks or faults within the system components.
- If equipped, check the charcoal canister for signs of saturation or damage that might affect its performance.
- Use a scan tool to monitor live data from the EVAP system while performing a drive cycle to observe any irregularities in operation.
